Title: Optical device
Inventor: YONEDA RYUJI
IPC: G02F1/37
Filed: 1995-04-28
Abstract: PURPOSE: To allow polarization inversion with the voltage as low as not to induce substrate destruction at the time of executing period polarization inversion by a voltage impression method and to make it possible to maintain sufficient strength by making the substrate thickness of a region where a waveguide is formed thinner than the thickness in other regions. CONSTITUTION: This optical device is constituted by forming the waveguide 18 on a substrate 17 having a nonlinear optical effect and forming the period polarization inversion structures within the substrate 17 including the waveguide. The thickness of the substrate in the region where the waveguide 18 is formed is made thinner than the thickness in the other region. Namely, the band-shaped waveguide 18 is formed on one main surface side of the substrate 17 having the nonlinear optical effect and a groove 13 is formed in the region along the waveguide 18 on the other main surface side. As a result, the thickness of the substrate 17 is made thinner in the region where the waveguide 18 is formed and, therefore, the breaking electric field intensity of the substrate 17 is improved and the polarization inversion voltage is dropped.  In addition, the easy execution of the polarization inversion is made possible, the polarization inversion regions are obtainable with good accuracy and moreover, the maintenance of the substrate strength is possible as well.

Title: Semiconductor optical modulating element
Inventor: KONO KENJI
IPC: G02F1/17
Filed: 1990-04-23
Abstract: PURPOSE:To lessen the influence of absorption of light arising from a fluctuation in a refractive index by providing an electrode for optical modulation in a part exclusive of the part right on an optical waveguide and modulating the refractive index in the peripheral part of the waveguide by using this electrode. CONSTITUTION:A function as a core part is obtainable in a mixed crystallizing region 4a and a function as a clad is obtainable in a non-mixed crystallizing region 4b. The refractive index of the mixed crystallizing region 4a is high to TM mode light and conversely, the refractive index thereof is low to TE mode light. The need for processing the waveguide for the purpose of confining the light in the waveguide is, therefore, eliminated. Since an electric field is not impressed to the mixed crystallizing region 4a having the highest light power density within the optical waveguide, a change in the light intensity arising from Kramers-Kronig relations is suppressed to a lower level. Further, the degree of coupling of the optical directional coupler itself can be changed and, therefore, there is no need for matching the coupling length of the directional coupler with the perfect coupling length thereof and the production is facilitated.

Abstract: PURPOSE: To perform various measurements with a singal construction by generating specified signals with a digital signal generator and a digital filter corresponding to the measurement of a selection level, flat level and SN employing an external input digital signal converted into the same two data.

Inventor: ISHIBAI KENJI
IPC: G06F3/0354
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To output an alarm or the like at every actual specified measured interval of time by controlling an accumulative time while deciding whether or not it is possible to accumulate the accumulative time in accordance with a length of the time interval of an operator's input operation to an input unit. SOLUTION: In a computer 400, input condition by a mouse 502 or the like from an operator is monitored at a monitoring processing part 401. When input operation is performed at shorter interval of time than a first specified time, the timing is always accumulated on a measured time. When the operator leaves his seat for other job or the like and there is no input operation from the first specified time to a second specified time, the time is excluded from the measured time. Also, when the input operation is not performed for longer than the second specified time, the measure time is reset.  Then, when a time of alarm comes, an operation start signal is sent to devices 500, 600 and 700 from a signal transmission part 402, and operation of a fatigue relaxation auxiliary device for generating a ultrasonic wave, vibration, a far infrared ray, music and the like for relaxing the operator's fatigue is started.

SOLUTION: A two-way valve control means A21 opens a two-way valve 14 by start of a compressor 10. Thus, liquid refrigerant retained in a shell 11 of the compressor 10 arrives at a flow limiting tube 15. The refrigerant is decompressed by the tube 15, and arrives at an evaporating tube 16. The refrigerant is evaporated in the tube 15, and pressure of the tube 16 is lowered. This is sensed by an evaporating tube pressure sensor 20. The refrigerant in the shell 11 is eliminated, and refrigerating machine oil 7 arrives at the tube 16. Then, the pressure of the tube 16 is raised. This pressure rise is sensed by the sensor 20, and output to the means A21. The means A21 closes the valve 14 by an output of pressure rise sensing of the sensor 20.

Title: Constant power control device for variable delivery pump
Inventor: ANDOU KUNIHIRO
IPC: F04B1/26
Filed: 1982-06-21
Abstract: PURPOSE:To prevent a circuit from heating due to the operation of a relief valve and save energy by automatically minimizing the discharge of a variable delivery pump through the operation of a cutoff control system when the discharge pressure of said variable delivery pump exceeds a set pressure determined by said control system. CONSTITUTION:The main elements of a cutoff control system (a) are a spool 39 whose outer end is applied to a pressure introducing passage 35, a spring holder 40, and a No.3 spring 41. When the discharge pressure of a variable pump 34 exceeds a prescribed pressure determined by the No.3 spring 41, the spool 39 is moved against the spring 41. As its land 44 passes through a pilot passage 45, a pressure-introducing passage 33 is connected to the pilot passage 45. Accordingly, a high pressure oil from a pump 1 flows into a pilot chamber 36 allowing a piston 18 to move further toward the left on the figure and minimizes the discharge of the pump 1 automatically, thereby preventing the circuit from heating due to the operation of a relief valve.

Abstract: PURPOSE:To suppress the self-resonance of a dust cap itself to reduce the interference in emitted acoustic waves, by forming the dust cap for a speaker with a low density polyethylene or a copolymer consisting essentially of ethylene, having specified densities. CONSTITUTION:A dust cap 11 for a conical speaker or the like is formed with a polymer of low density polyethylene having 0.92-0.94 specific gravity, a copolymer consisting of essentially of ethylene, for example a copolymer of ethylene and vinyl acetate.

Further, since the Young's modulus is large, the hanging-ball oscillation or the like is suppressed by the auxiliary function of parts of the oscillating system to prevent the generation of abnormal sounds and the break of the insulating film of a voice coil.

Title: Synchronous amplifier
Inventor: HASEGAWA KAZUO
IPC: H03F3/08
Filed: 1992-04-24
Abstract: PURPOSE:To enable large dynamic range and the high stability of a DC operating point by low power supply voltage and at low cost by decreasing the signal negative feedback amount of a direct-coupled reverse amplifier circuit during the supply period of a detection signal and increasing it during the non-supply period. CONSTITUTION:When an LED 18 is driven by a timing generation circuit 15 and an optical sensor 11 outputs a detection signal, the negative feedback to the input end of a direct-coupled reverse amplifier circuit 1 via an AC feedback circuit 2 is performed for the part of the output signal obtained by a signal output terminal 6. In this case, a switch 20 is turned off, a series resistance increases and the negative feedback amount decreases in the circuit 2, and the gain in the circuit 1 increases. At the time of the non-supply of a detection signal, the switch 20 is turned on, the negative feedback amount increases and the gain decreases. Thus, the device where a DC operating point does not fluctuate is obtained by dissolving the saturation due to the input of an excessive signal at low cost and in a short time.
